Abstract of the 140th meeting of CCEP

 The 140th meeting of the Coordinating Committee for Earthquake Prediction (CCEP) was held at the Kanto Regional Survey Department of the GSI on Nov. 24,2000. Universities and national research institutes reported and discussed the results of observations and investigations about seismic and crustal activities in Japan. Main topics of discussions are listed below.

• Seismic activities of Japan.
  • fig. 1 Earthquakes of M5 or greater in andnear Japan. (JMA)
• Crustal deformations by the earthquake and the volcanic activity of the Izu islands.
  • fig. 2 Seismic activities around the Niijima, Kouzujim, and Miyakejima. (ERI)
  • fig. 3 A model of explanation of the volcanic and seismic activities in the Izu islands region. (KMogi)
• Seismic activities and the Crustal deformations of the Tokai district.
